Originaly a jitney was an African who wears their traditional tribal dress (especially in a setting that it looks out of place- eg. a city) however the word can also be used as a general term for someone who wears traditional dress or just stands out from the crowd.

I was watching a show on Cape Town and in there were a group of Jitneys on the street when everyone else was wearing suits

Jitney lifestyle is not to be confused with farming or farmers. Jitney dwellers are commonly seen among aging rural families. Jitney's have more in common with White Trash, Hillbillies, Crackers and Rednecks. Jitney's are the bombed out shells of once aspiring northeastern families. Many Jitney families once had dignity; such dignity existed in prior generations where parents taught values, morals, and lessons of working hard and saving for the future. Such lessons of savings have been misinterpreted into collecting Jitney, hence the encompassing translation of jitney.
